' It is generally known among automobilists that in motoring up a steep grade, 7 through heavy snows, on a long uninterrupt supply and oftentimes, to replenish a great deal ofthe Water supply that has escaped through evaporation caused by boiling and steaming. f

My invention relates to condensers for radiators of the type that may be readily applied or removed from-the radiator, and has for an object to provide means for conserving the water supply of the radiator by avoiding the wastage thereof byevaporation or ejection through the overflow pipe due to expansion by heat, and the scope of my invention extendstowhatever construction may be defined by or included Within the terms or language of the appended claims.

In the drawing: 1 V I Figure 1 is a view in perspective of my improved radiator condenser as applied to a radiator;

Figure 2 is a central longitudinal sectional J view thereof;

Figure 8 is a detailcross line 33 of Figure 2, and

Figure 4 is a detail sectional view on the line 44 of Figure 3.

My invention, in the form of embodiment shown in the drawing and briefly described, comprises a novel condensing device 10, which maybe used in connection I with the ordinary or usual radiator filling cap 11. Although the condensing device 10 maybe of any' desired form or shape, I have illustrated it as conforming gener ally to the contour or outline of the radiator to which it is attached. I

The condenser 10 consists of an upper compartment 12 and a lower compartment 18, and a plurality of vertically extending tubes let providing communication between the compartments. VVater-tight connection is of course, provided between the tubes l i and the compartments 12 and 18 by soldering or any other desired manner. v

For equalizing the cooling of the vertical section on the tubes 14, I provide a plurality of horizontally extending relatively thinmetallic strips 15 which may beheld in their spaced relation by, soldering or other suitable means; These plates are, of course, pro* vided with suitable'openings for the passage of the tubes 140 I y My improved condensing device is fur ther provided with end walls 16 which-not only connect the upper and lower compartments 12 and 13, but they serve to form" a continuous and attractive supporting frame constituting the various desired designs.

The body portion of my condensing device 10 is provided with downwardly extending tubular. portion 17 and provided at its lower end with a reduced portig 17a" WlllClllS adapted to pass through the usual radiator cap 11, and is securely held in p0sition by means of a suitable nut 18." By securing my improved device to the radiator cap in this manner, it Will be seen that Imay readily apply it to any desired form of cap, by Tendering 1t 2. very necessary accesi so sory. l

For conveying the-vapor from the upper portion of the radiator to my conde-nser'l provide a vertically extending tube 19, which passes through the tubular portion 17, the chamber or compartment 13, the strips 15, and into the upper compartment 12; The

- tube 19 preferably is extended to within a short distance of the top of the chamber 12, and forms'the outlet for the vapor from which point it is drawn downwardly through the tubes 1 1 in which the vapors are condensed. The liquid now passes down, collects inthe lower chamber 13 andis returned to the radiator through the downwardly eX- tending-pipe 20, which is substantially of smaller diameter than the tube-19,

To prevent the premature condensing of the vapor as it passesthrough the tube 19,

which would prevent the easy passage of the.

vapor through the tube, I pack asbestos or other suitable insulating material within the tubular portion 17 of the lower end of the compartment 13, as is clearly shown in Figures 2 and 3 as at 21.

It is to be understood that I may readily construct my device in various shapes or form in order to conform to the different designs or outlines of various hoods, which would be striking and effective in appear ance.
